Description
A colorless gas that smells like rotten eggs. Hydrogen sulfide occurs as a component in natural gas, volcanic gas, and sulfur springs. It is also produced as an air pollutant due to the combustion of sulfur containing coal and the organic decay of manure. Hydrogen sulfide can also be emitted from some paints, textiles, and vulcanized rubbers. As a component in air pollution, it is responsible for tarnishing silver and blackening lead pigments. Commercially, hydrogen sulfide is used as an antiseptic and a bleach.
